I've got a Beneteau 40 and one of the latches in the galley has a busted spring. i'm hoping someone can direct me to where i can get a suitable replacement. The door has a round hole with the trigger for the latch 'sealing' the back of the hole. When you stick your finger in, it pushes the trigger which makes the latch arm swing DOWN, yes down. The elbow latches i find in West Marine won't do the job. Please help.
